1. Overview
The SYM water pressure pulsation device takes the single-chip microcomputer as the core processing unit, and is equipped with a pulsating pressure transmitter to monitor the pressure pulsation status of the measuring point in real time, collect and process the pressure pulsation value, accurately display the water pressure pulsation change of the measuring point, and at the same time can Output the corresponding analog quantity. When the water pressure pulsation of the measuring point exceeds the preset value, an alarm signal can be issued. Water pressure pulsation monitoring can enable operators to understand the working conditions of the unit and optimize the operation of the unit.
2. Features
The intelligent monitoring device with single-chip microcomputer as the core processor has strong applicability.
Output the standard analog signal corresponding to the range.
Provides alarm status display and secondary alarm output contacts, and the secondary alarm value can be set independently.
Switchable display of peak-to-peak value (PV) relative value (%) and real-time value (Mpa) of water pressure pulsation.
With power-off protection, automatic memory function.
Perfect system self-check function.
The working power supply (+24V) of the transmitter can be provided.
3. Technical performance

4. Working principle
The water pressure pulsation device is composed of pressure transmitter, monitoring instrument and connecting cable. The pressure pulsation signal output by the transmitter is sent to the single-chip system for processing after signal processing. The processed data is displayed and converted into 4~20mA analog output. When the monitored pulsation value exceeds the limit, the first and second level alarms will be output respectively.
